Existence and uniqueness of periodic orbits in a discrete model on Wolbachia infection frequency

open access: yesAdvances in Nonlinear Analysis, 2021
In this paper, we study a discrete model on Wolbachia infection frequency. Assume that a periodic and impulsive release strategy is implemented, where infected males are released during the first N generations with the release ratio α, and the release is

On the Dynamics of Sexually Transmitted Diseases Under Awareness and Treatment

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
In this paper, we develop and extend the work of Jia and Qin on sexually transmitted disease models with a novel class of non-linear incidence. Awareness plays a central role both in the susceptible and the infectious classes.

Bayesian Inference for SIR Epidemic Model with dependent parameters

open access: yesMoroccan Journal of Pure and Applied Analysis, 2022
This paper is concerned with the Bayesian inference for the dependent parameters of stochastic SIR epidemic model in a closed population. The estimation framework involves the introduction of m − 1 latent data between every pair of observations. Kibble’s

Determination in Galicia of the required beds at Intensive Care Units

open access: yesAlexandria Engineering Journal, 2021
By using a recent mathematical compartmental model that includes the super-spreader class and developed by Ndaïrou, Area, Nieto, and Torres, a procedure to estimate in advance the number of required beds at intensive care units is presented.

Central limit approximations for Markov population processes with countably many types [PDF]

open access: yes, 2012
When modelling metapopulation dynamics, the influence of a single patch on the metapopulation depends on the number of individuals in the patch. Since there is usually no obvious natural upper limit on the number of individuals in a patch, this leads to ...

Establishment of clinical criteria for the diagnosis of adverse food reactions in dogs with atopic dermatitis

open access: yesVeterinary Dermatology, Volume 35, Issue 4, Page 418-431, August 2024.
Background – Diagnosis of canine adverse food reactions (AFRs) is based on vague criteria, such as ‘>50% improvement’ during elimination diet trial (EDT) followed by ‘deterioration’ during provocation test (PT). Objective – The objective of the study was to use predefined criteria to evaluate response during EDT [i.e., Owner Global Assessment of ...

Are the upper bounds for new SARS-CoV-2 infections in Germany useful?

open access: yesComputational and Mathematical Biophysics, 2021
At the end of 2019, an outbreak of a new coronavirus, called SARS–CoV–2, was reported in China and later in other parts of the world. First infection reported in Germany by the end of January 2020 and on March 16th, 2020 the federal government announced ...

From pandemic to a new normal: Strategies to optimise governmental interventions in Indonesia based on an SVEIQHR-type mathematical model

open access: yesInfectious Disease Modelling, 2022
There are five different forms of intervention presently realised by the Indonesian government in an effort to end the COVID-19 pandemic: vaccinations, social restrictions, tracings, testings, and treatments.

Stochastic epidemic SEIRS models with a constant latency period

open access: yes, 2017
In this paper we consider the stability of a class of deterministic and stochastic SEIRS epidemic models with delay. Indeed, we assume that the transmission rate could be stochastic and the presence of a latency period of $r$ consecutive days, where $r ...
